In day-to-day matters, common sense serves us well and is usually better than needlessly complicated explanations. We don’t need to know, for example, exactly how fast a car can go in a rainstorm before the tires begin to lose contact with the road. Somewhere there’s a mathematical formula that would allow us to know the answer with great precision, but our common sense needs no such formula to tell us to slow down in bad weather, and that’s good enough.
